ammoxylon, 6 Burmanni, DC. prod. 2. p. 353.—Burm. Zeyl. t. 82 (good). ` 
Tanjore, frequent, in dry arid soil. Rare in the north of the Peninsula. 
I.argentea, Linn.! is not found in India: it has the leaflets opposite 
and legumes much compressed, and is quite distinct from the present spe- 
cies. 
631. (15) I. mysorensis (Rottl. :) shrubby, erect, branched : branches as- 
cending, terete, hirsutely villous : leaves pinnated : leaflets 1-8-pairs, elliptie- 
oblong, mucronate, strigose on both sides with adpressed pubescence: ra- 
cemes sessile, elongated, many-flowered : flowers distant, solitary in the axils 
of large foliaceous! bracteas: calyx-segments lanceolate: legumes terete, 
pointed, erect, hirsutely villous, 3—4-seeded ; seeds reniform.—Herb. Heyne! ;

Dr Wallich has remarked in his List, “Spreng. vix DC." which called our 
attention more partieularly to the characters given respectively by these au- 
thors; and by a comparison of the specimens in Heyne's herbarium, we are 
now enabled to account for their apparent discrepancies. In the one series 
(I. mysorensis, Heyne and Wall. L. 5459. a), the inflorescence is little ad- 
vanced, and the specimens well covered with pinnated leaves ; there is also 
a trifoliolate leaf at the base of each raceme. The other series (F: polyphylla, 
Heyne, or Wall. L. n. 5459. b), are much more luxuriant, and the racemes 
haye become so much developed as to resemble young branches ; the brac- 
teas have enlarged in proportion, and resemble simple leaves. The former 
corresponds to Sprengel’s character : the latter to that given by De Candolle, 
who probably had only seen the top shoots, for, on the lower part of the 
specimens we have seen, pinnated leaves are also observable. 
632. (16) I. Wightii (Graham:) suffruticose, erect, branched, all over 
hoary with adpressed silky hairs ; branches ascending, striated: leaves pi- 
nated ; leaflets 5-10-pairs, small, oblong-oval, slightly retuse, mucronate : 
racemes rather shorter than the leaves, many-flowered : flowers small, crowd- 
ed, manyfof them deciduous : calyx-segments short, and acute : legumes few, 
towards the apex of the rachis, erect, cylindrical, stout, straight, acumina 
10-12-seeded : sutures prominent : seeds cylindrical, truncated at both ends.

e specimens we have from Rottler's herbarium, and marked J. polyphylla, 
although obtained from Heyne, yet differ from those so named by Heyne and 
distributed by Wallich: Dr Graham informs us that they accord precisely . 
with his I. foliosa, which it seems Dr Wallich only had from the Calcutta 
Bot. Garden : we have not, however, examined the latter ; it is probable that 
it may have been raised from seeds transmitted by Heyne. 
633. (17) I. tinctoria (Linn. 7) suffruticose, erect, branched, sprinkled with 
short whitish pubescence ; branches terete, firm: leaves pinnated ; leaflets 
5-6-pairs, oblong-obovate, cuneate at the base, slightly decreasing in size to- 
wards the apex of the leaf: stipules subulate, erect or incurved : iron 
ma 
at the base of the raceme, more distant and deciduous towards the upon 
calyx-segments broad, acute: s gee approximated towards the base © the 
rachis, nearly cylindrical, slightly torulose, deflexed and more or less curv!
